PERFORATING MACHINE Frederick H. M. Hart, Poughkeepsie, and Clement Ehret, White Plains, N. Y., assignors to International Business Machines Corp., New York; N. Y., a corporation of New York Application December 19, 1935, Serial No. 55,180 l' 20 Claims.

This invention relates to perforatlng machines adapted to prepare perforated cards for use in the operation of calculating machines rsuch as sorting and tabulating machines.

One object of the invention is to devise a machine of this type which will cut the cards into desired sizes on the completion of the punching of the data in the cards.

L Another object is to devise a punch of this type in which cards of diierent sizes may be prepared in the same machine.

Another object is to devise means whereby a record card of a given length may be cut into severalsmall cards and the perforations in each of these small cards made at a predetermined distance from an edge of the card. y

.Other objects will appear in the following description ofthe invention.

Referring to the drawings:

Figs. l2 and 13 are sectional details of a card gripper;

Fig. 14 isa diagrammatic view illustrating the manner in which a card of given size vmayloe cut into several small cards of varying sizes;

Figs. 15, 16 and 17 illustrate the manner in positionsjon a record cardt' The'punchesco operate with punch dies 2a. The card is fed column by column under this row of punches and .the operation of one of the keys 3 will depress a corresponding lever 4 pivoted at 5 and resting on the top of the particular punch 2. This depresses the punch, against the action of its spring 6, to punch a hole in one of the 12 positions in the column.

Card feed The feeding of the card with respect to the punches is effected by a card gripper 'I mounted on a bracket 8 fixed to a r'ack bar 9 lhaving gear teeth I0 along its lower edge as shown inV Figs. 2 and 4. Teeth I (l mesh with a gear I I operated by a spring drum I2. Movement of the rack 9 of the card carriage from the left to the right effects tensioning of the spring which thereafter tends to return the carriage to the left.

The escapement pawl mechanism of Fig. .4,'cooperating with ratchet teeth. I3 carried by the carriage rack 9, holds the card carriage in position until operated to release the carriage to escape a distance of one or more columns.y The` pawl M of the escapement, pivoted at I5, normally holds the carriage in position. When one of the keys 3 is operated to depress the bar li, the latter. resting on' a bail i6 reaching under all of the bars d, will be rocked downwardly on its axis l5. This lifts pawl it out of the ratchet teeth i3. At the same moment 'a pin Ill rocks a holding pawl i8 into mesh with the ratchet teeth i3. As the key is released the pawl ld reengages the teeth i3 and pawl lli disengages and the carriage escapes a single column'. i

-lt is, ofcourse, understood that the pawl lli jumps forward slightly when it islifted out of the rack so that when it moves back into the rack it reaches over the teeth which it had previously been holding and the carriage jumps to the. left until the next tooth is stopped by the pawl. This escapement mechanism Ais well known in this art and need not be'de'scribed in all of its details.

As viewed in Figs. 3 and 5, the stepping pawl Mi cooperates with one edge of the ratchet rack i3 and the holding pawl it with the other edge. 'lf'hus by cutting out part of several of the ratchet lteeth as at 69 when this portion of the rack"v reaches the pawl l@ the carriagewill skip a distance equal to the extent of the mutilated portion Vof .the rack. As shown in Fig. l5, the rack has one mutilated portion l@ While the rack in Fig. 16 has 'two such mutilated portions and the rack in Fig. 17 has'three mutilated portions. The rack l`3 is detachably mounted von the carriage rack ii so that diii'erently-Ucut racks may. he` attached depending uponthe places in'whichlthe'cardsareto' be cut. I1 a full length card is .to be'cut into two smaller cards as in Fig. 15 then a rack having one mutilated portion I9 is placed in the machine. If the card is to be cut into three sections then the rack in Fig. 16 is placed in the machine, etc. These racks are provided with notches 20 adapted to tit over studs 2I having heads as shown in Fig. 2. A shoulder 22 (Fig. 15) is adapted to snap under a cooperating shoulder 23 on a ilat spring plate 24 xed to the carriage bar 9 to hold the rack rigidly mounted on the carriage.

When dividing a card of given dimension into various smaller sizes, it is necessary that the columns of perforations on each card shall be the proper distance from one edge of the card in order to cooperate correctly with the perforation sensing elements of sorting and tabulating machines. Inthe present instance, the perforations may occupy positions arbitrarily measured from the left edge of the card. For this reason, it may be necessary to make a correction in the increment of feeding between the last column on one card section and the rst card column on the next section. In other words, the teeth in the rack I3 are equal to the distance between adjacent columns on a card. If the entire card of Fig. 15 is to be punched as one card then the teeth of rack I3 continue with equal spacing throughout the entire length of the bar. But where the card is to be split into two as in Fig. 15 the distance between the last column on one of the card sections and the first column on the following section is not equally divisible by the distance between two columns. 'Ihe correction is made by increasing or decreasing the distance between two of the teeth as at 25, so that when the carriage comes to rest after skipping over the gap I9, the escapement rack will be stopped in position to present the first column on the second section of the card, in position under the punches so that the perforations will be made the same distance from the left edge of the second card as in the case of the rst card. This correction may be made in each of the several racks at each of the mutilatedportions I9 thereof.

In order to skip certain columns on a card, that is, on one of the various smaller cards, the skip cam bar 26 common to these machines may be employed. These skip bars are provided with raised sections 21 and depressed sections 28 along their upper edge (Fig. 6). A skip lifter bar 29 shown in Fig. 4 reaches out over the edge of the cam bar 26 which is mounted on the carriage 9 on studs 30 similar to the mounting of the escapement rack on the carriage. The skip lifter 29 isrender the escapement pawl I4 and as the cam bar .26 moves step by step, when a raised portion 21 thereof reaches the skip lifter 29, if the X key is depressed it will move the lifter and the latter will be raised by the cam bar and raise the pawl I4 out of the escapement teeth I3 and the carriage will move freely until the raised portion 21 rides out from under the skip lifter 29, permitting the pawl I4 to reengage the escapement rack I3. l

The carriage may be caused to escape a single column without punching, by depressing the space key 3l. This key is carried by an arm 32 pivoted at 33 and connected at 34 to a link'35 adapted to rock the escapement pawls in the usual manner to effect the single column escapement (Figs. 4 and 6).

In order to release the carriage so that it may move freely the full distance to the left. a skip The restoration ofende sa 1s effected through an arm 40 fixed on a rod 4I (Fig. 6) on which is also fixed an arm 42 connected by spring 43 to an arm. 44 pivoted at 45 and ilxed with red,spect to an arm 49 connected by a link 41 to an arm 49. Arm 48, (Fig. 6) is xed with respect to arm 48a pivoted at 48h. Arm 48a reaches up into a path oi a shoulder 49 on the carriage bar 9 (Fig. 2) so that as the carriage reaches the end of its travel to the left, it will rock the arm 48a, pulling the rod 41 of Fig. 6 to the left, rocking arm 44 counterclockwise and through spring 43 rocking arm 42 downwardly and arm 40 to the left, to restore the slide 39 to the position of Fig. 7. A spring 59 (Fig. 6) normally tends to rock arm 46 clockwise to hold the arm 48a in its normal positions.

Card gripper The card gripper or clip which feeds the card to the left, is shown at 1 mounted on the bracket 8 which is fixed to the bar 9 to form the card carriage. This gripper is provided with upper and lower jaws 5I, 52 (Figs. 12 and 13). The lower jaw 52 is fixed to a sliding block 53 slidable in groove 54 of the fixed block 55. 'I'he upper jaw 5I is pivoted at 56 to the block 55 and is adapted when raised, to engage an upward projecting portion 51 of the sliding block 53 so as to move the lower jaw 52 to the left as viewed in Figs. 12 and 13. A spring 58 tends to rock the upper jaw downwardly to closed position to grip the edge of a card. When this takes place, a spring 59 presses the projection 51 to the right and moves the lower jaw 52 into position with respect to the upper jaw and below the edge of the card.

Fixed with respect to the upper jaw 5I is a rearwardly projecting arm 60 adapted to be held in its lower position as in Fig. 12 by a latch 6I. The latch 6I is pivoted at 62 and is provided with a compression spring 63 adapted to rock it into latching position. A key 64 reaches downwardly and engages the top of the projecting arm 60 and is adapted to press arm 60 to its lower position, thus opening the jaws of the gripper, and the latch 5I will latch the parts in open position.

When the carriage is moved to the right with the jaws in openvposition, the latch member 6I comes to rest under a nger 65 carried by an arm 86 pivoted at 61 and fixed with respect to an arm 68 connected at one end to link 35, which as we have seen is connected to the escapement mechanism. When any one of the punch keys is operated and operates the escapement mechanism, the finger 65 is rocked downwardly to depress the latch 6I. Ihis releases the jaws and permits 4them to close and grip the card so that when the carriage now escapes, it will take the card with it to effect column by column feeding. Operation of the skip key 3I which as we have seen lifts the link 35 to operate the escapement, will also eiect closing of the jaws of the card gripper.

The block 55 of the gripper is mounted to slide ,as the operator moves the key to the right the 'oted at 12 and fixed with respect to arm 13 (see also Fig. 11) is adapted when the arms 13-1I rock, to raise the clips \in bracket 8. Arm 13 is connected to a key 14 carried by the .bracket 8. 'Ihe operator, in returning the carriage from the left to the right in the machine, presses the key 14. This first lifts the card gripper assembly above the surface of a card in the machine and entire carriage with the card gripper is moved in this direction. I

When the carriage has been moved its full distance to the right the jaws of the card gripper will be in position to engage the left edge of card 15 which has been placed in the machine. The card is pressed by a spring-actuated stop l16 into engagement with the card gripper. As soon as one of the keys is depressed, it will rockthelatch member 6|, releasing the jaws so that they will close upon the card las in Fig. 13. When the card carriage reaches its position to the right andthe key 14 is released to lower the grippers into position to grip the new card, the rear edge 11 of the gripper assembly will be in position to engage the right edge of the cards which have been cut and remain in the positions shown in Fig. 6. As the new card is now punched andthe carriage steps to the left, the gripperv will push the cut cards along with it so that when the carriage reaches the end of its travel to the left the cards will have been pushed intothe stacker 18 as in Fig. 6.

A projection ||6 (Fig. 3), connected to a slide I I 1 carried on the outside of the stacker, is adapted to stack the cards. A pin 8 (Fig. 2) reaches from the slide ||1, into-engagement with an arm into closed position as in Fig. 10. 'Ihe part 19h ||9 on arm 48a. When the gripper moves tp the left it will engage thev projection IIB near the'` end of its stroke and move it to the left, pushing the punched cards into stacked position 'I'he cutting of the cards is effected'by means of cutting dies 19 carried by the base frame of the machine, working in cooperation with hinged knives carried by a frame 8| hinged at 82 to a bracket 83 xed to the base I. Each cutting die is made up of two parts 19a, 19b. The part 19a of the die is xedin the base ofthe machine and the part '19h is slidable therein, being provided with a guide tongue 84 sliding in a groove inthe fixed part 19a.

Normally the parts are in the open position shown in Fig. 9 so that as thecard carriage moves from the right to the left with a card which is being punched, the gripper travels through the v is fixed to va rod 85 by means of a bracket 81 integral with the tongue 84. The rod 85 is slidable in the base of the machine and is provided with a compression spring 88 pressing against the bracket 81 at one end and against the frame of the machine at the other. 'Ihe spring'tends to move the rod with'the part. '19h to the left as After the carriage has reached viewed in Figs. 8A and 9 to move the part 19h lto the closed position of Fig. 10. The right end of rod 85 is provided with an upwardly projecting arm 88 xedthereto. Arm 88 is adapted to be actuated by a cam 89 fixed with respect to the rocking frame 8| so that when the latter is raised,` the cam will move the member 88 to the right (Fig. 8) to move the die portion 19h to the open position of Fig. 9.

A latch 90 pivoted at 9| and actuated bya compression spring 92 will cooperate with the upper end of member 88 to hold the parts in open position. When the rocking frame 8| is lowered a projection 93 fixed thereto will engage a pin 94 in the latch 90 and rock the latter to release the member 88 so that the spring 86 will close up the cutting dies. 'I'he parts are so adjusted that this closing takes place before thevcutting knives reach the cutting dies.

'I'he cutting knives 80 are fixed to arms 95 pivoted at 82 so as to swing with the frame 8| when the latter is opened and closed. A spring 98 is associated with each cutting knife and tends to hold the latter in raised position 96al of Fig. 8 so that when the frame 8| is lowered, the knives will not cooperate with the dies to effect cutting of the card'. Levers 91 pivoted at 98 are adapted, when rocked clockwise as viewed in Fig. 8, to lower the knives to the position 96h so that when the frame 8| is lowered the knives will cooperate`v with the dies to cut the card. Associated with' each knife 80 is a corner cutting knife portion 99 adapted to cooperate with the oblique edge portion |00 of the die part 19h so as to cut olf one corner of each of the cards as indicated at |0| in Figs. 14 to 17. As disclosed, there may be four cutting dies 19a-19h, and four cooperating cutting knives 80. 'I'he knives as well as the dies are spaced as shown in Fig. 14 so that if a full length card is to be cut' into two parts, the knife designated 4--2 will be released lfor operation', by the setting of proper lever 91 of Fig. 8. When the frame is lowered this knife alone will cut the card 152 along the line |02. If the card is to be cut into four equal parts then three of the knives, designated 4-3, 4-2 and 4 willbe set to operate and will out the card 154 along the lines |03 as in Fig. 14. If the card is to be cut into three equal portions the knives designated 4 3 and 3 will be set to operate and the card carriage will be permitted to move slightly farther to the left so that the card 15a will'ibe cut along the lines |04.

'Ihe setting of the carriage to cut the card into two or four portions on one hand, or into three portions on the other, is controlled by a stop member |05 (see Fig. 2) pivoted at |05 to the frame of the machine. When the stop is in the positionv of Fig. 2. the left end |01 of the carriage will strike the shoulder |08 of the stop |05. 'I'his sets the carriage in position to cut the card into two or four parts. rocked to the dotted line position of Fig. 2, the carriage is free to move until it engages the fixed stop stud |09 and will be in position to effect cuttingA of the card in three parts. is carried by a plate ||0 pivoted at to the frame of the machine and adapted to be rocked on its pivot so as to effect a fine adjustment in the setting of the stud |09 which is off center with respect to the pivot ||I. The plate ||0 cooperatesv with a setting screw ||2 through a slot so that the plate may be moved to the proper position and xed in such position by tightening of the screw. 'This sets the stop stai-d When the stop |05 is 'I'he stop |09 |09 in accurate position for the setting of the carriage to cut the card into three parts. It also accurately determines the position of the movable stop |05 to stop the carriage in position for the cutting of the card into two or,four parts.

A pair of spring pressed fingers ill may be carried by the rocking frame v8i to press uponthe card as the frame is lowered for cutting, 'to hold the card firmly in position while it is being cut.

An arm ill fixed to the rocking frame 8i is adapted to reach over the top of key I4 when the rocking frame is lowered to efi'ect cutting. This depresses the key 64 and effects the opening of the jaws of the card gripper so that after the card has been cut and the rocking frame is raised out of position and the operator presses key 14 to move the carriage to the right, the gripping Jaws will have released the card so that the gripper may now be raised above the surface of the card to move freely over the card when the carriage is moved to the right. l

A handle H5 is provided on the frame 8i so that the latter may be readily manipulated.

A projection i20 on the frame 8| may be provided to cooperate with a shoulder I2I on the base of the machine, to prevent twisting of the frame 8l while the card is being cut.

As shown in Fig. 1, a roll |22 of stock may be provided to feed the card stock to the machine, instead of using individual standard size cards to be cut into smaller cards. A roller |23 may press lightly on the stock to hold it in place without interfering with feeding.

It will be understood that cards may be cut into other lengths than those shown in Figs. 15, 16 and 17. For instance, the card of Fig. 16 may be cut in one place instead of two, to produce one card a third of the standard length and one of two thirds standard length. Or, if the stock is being fed from a continuous strip, all cards may be cut two thirds standard length. In like manner, the

card of Fig. 17 may be differently cut or cards of varying lengths produced from a reel.

While there has been shown and pointed out the fundamental novel features of the invention as applied to a single modiiication it will be understood that various omissions and ysubstitutions and changes in the form and details'of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
